APPARATUS FOR BACKING BOOKS.

Application filed September 19, 192.4.

To all whom it may concern Be it known that I, LOUIS WV. Mnxnns, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Apparatus for Backing Books, of which the following is aspecification.

This invention relates to the manufacture and repairing of books, andmore particularly to a machine for backing books.

In backing books of different thicknesses, the radius of the cur e onthe back of the book varies according to the thickness of the book andit is desirable to provide some means for automatically adjusting thebacki ng roller to books of. different thicknesses.

In the present invention, I provide a machine having a backing rollerand means for automatically adjusting the radius of the roller accordingto the thickness of the book.

More specifically, I provide a vise adjustable on the bed of the machineadapted to receive the book to be backed and a frame in which thebacking roller is mounted, the frame being pivotally mounted on rollersand being connected to the two jaws of the vise by links, whereby thepivot of the frame will change as the aws of the vise are moved withrespect to each other.

In the accompanying drawings, I have shown one embodiment of theinvention. In this showing:

Figure 1 is a front elevation of the machine,

Figure 2 is a horizontal sectional view of a portion of the machine online 22 of Figure 1,

Figure 3 is an end elevation,

Figure 1 is a vertical sectional view through the roller elevating meanson line 414 of Figure 3, and,

Figure 5 is an end view of a book before and after backing.

Referring to the drawings, the reference numeral 1 designates the legsof the machine adapted to receive and support a bed 2. A vise is mountedon the bed and it consists of a stationary jaw 3 having a vise plate 41-arranged thereon and a movable jaw 5 having a vise plate 6 arrangedthereon. The movable jaw is provided with a nut 7 secured to its rearface by means of bolts 8 and a vise screw 9 passes through this nut. Thescrew is mounted in a suitable bearing Serial No. 738,713.

10 and is provided with a hand wheel 11 at its outer end to permitadjustment of the movable jaw; The book to be backed is arranged on thebed of the machine between the jaws of the vise, as indicated in dottedlines at A in Figure 3 of the drawings.

The backing roller is mounted in a frame, consisting of side members 12.These side members are pivotally mounted on the pins or rollers 13. Therollers 13 are connected to the inner ends of compensating links M andthe outer ends of these links are pivotally mounted on pins or bolts 15,carried by the two jaws of the vise. A counterweight 16 is arrangedbeneath the pivot 13.

r shaft 17 is mounted in the top of the frame, being supported insuitable bearings 18 and this shaft is provided with a hand wheel 19 onits out-er end. Bevel gears 20 are secured to the shaft adjacent eachend and these gears mesh with similar bevel gears 21 mounted on theupper ends of vertical shafts or screws 22. The upper shaft 17 isprovided with a retaining collar 23 which is secured thereto by means ofa pin 241 and is adapted to prevent longitudinal movement of the shaft.

The shafts 22 extend downwardly to a point adjacent the pivots 13 andare provided with threaded portions 25. These threaded portions extendthrough nuts 26 carried by roller boxes 27. A roller 28. is arrangedbetween the roller boxes and a bushing 29 is arranged in each end of theroller. The bushing is adapted to receive a shaft 30, the end of whichis received in the roller box.

In operation, the book to be backed is first formed, as shown at B inFigure 5 of the drawings and has a straight rear edge 31. It is thenarranged in the vise in the usual manner, as shown in Figure 3 of thedrawings and is clamped in position by means of the hand wheel 11. Itwill be apparent that the movement of the jaws of the vise causes thecompensating links 1 1 to move, outward movement of the jaw 5 tending tocause the links to assume a horizontal position, and inward movement ofthe movable jaw causing the links to assume an inclined position andraising the pivot pins 13. After the book has been clamped in the vise,the roller 28 is lowered through the medium of the hand wheel 19, theshaft 17 and the screws 25. Vhen the roller engages the back of thebook, the frame is swun on the pivots 13, as indicated in dotted linesin Figure 3 of the drawings. This rolls the back of the book in thedesired manner and forms a book, as indicated at C in Figure 5 of thedrawings, having the back edge rolled, as indicated at 32. It will beapparent that the pivot pins 13 will move upwardly as the jaws of thevise approach each other and the arc traveled by the roller inengagement with the back of the book will decrease in proportion to theproximity of the jaws to each other. By the employment of links 141 ofproper size, the adjustment of the radius may be in accordance with thestandard practice to ive the desired radius to books of differentthicknesses. As the links 14 are of the same length, the pivots 13 willbe at an equal distance from the jaws of the vise at all times.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

I claim:

1. In a device of the character described, a vise, a frame pivotallymounted over said vise, a vertically adjustable roller carried by saidframe, and means controlled by the movement of the jaws of the vise forshifting the pivot of the frame.

2. In a device of the character described, a vise, a frame arrangedadjacent said vise, a vertically adjustable roller carried by saidframe, links connected to the jaws of said vise, and pivot pins carriedby said links and supporting said frame.

3. In a device of the character described, a vise, a frame pivotallymounted over said vise, ahorizontally extending shaft carried by saidframe, vertically extending shafts arranged at opposite sides of saidframe and connected to said horizontally extending shaft to be rotatedthereby, said shafts being provided with threaded portions, roller boxesmounted on the threaded portions of said shaft, and a roller arrangedbetween said boxes and supported thereby to permit rotation.

4. In a device of the character described, a vise, links connected tothe jaws of said vise, pivot pins connected to the ends of each pair oflinks, a frame pivotally supported on said pins, a horizontallyextending shaft arranged in the top of said frame, vertical shaftsarranged at each side of said frame and connected to said horizontallyextending shaft to be rotated thereby, said shafts being provided withthreaded portions, and a roller arranged between said shafts and adaptedto be vertically adjusted by the rotation of said shafts.

In testimony whereof, I aiiix my signature.

LOUIS w. MEYERS.
